"eDPI" is a useless concept, and has absolutely no value in games like PUBG. The reason is simple, PUBG (and many other games) do not have a 1:1 relation between sensitivity value and 360 distance. In other words doubling the DPI and halving the sensitivity does not equal the same 360 distance.
These games usually have zero as a valid sensitivity, so obviously doing DPI*sensitivity doesn't work.
So yes, it's safe to use this new sensitivity.
